The order in which we implement features is determined by the "bang". This is your votes divided by a time estimate (specification + implementation time).

A simple feature will have a time estimate of "1". A more complex feature that takes 20 times as long to implement has an estimate of "20", and needs 20 times as many points as the simple one before we address it.

Of course the bang is not the only thing that influences us, we also see our role in making the final decision. But we need strong arguments if we postpone a feature with a high bang.
